Terrestrial Vehicular Communicatons via Microwave and Optical Wireless (WTZ-Kooperation) - Terrestrial network offloading for enhancement of vehicular communicaton through integraton of microwave with optcal wireless communicaton (Project Nr.: IN 11/2022)

Project: Research project

Project Details


In this project (WTZ Co-operation between India and Austria), our focus is on traffic based selection and allocation of resources considering the line of sight LOS and non-line of sight NLOS conditions. The following rule for resource allocation is proposed. In low traffic, the load on the terrestrial network is low on the account of low user density. Thus, microwave links are supposed to be reliable and sufficient. In a high traffic scenario, the speed of each vehicle would be less than that in case of a low traffic scenario. In this case, the total load on the network would be high on the account of high user density. Thus, resources from high capacity optical wireless bands need to be activated/assigned. In addition to the service through optical wireless band spectrum, one microwave link will be provided to take care of NLOS users. Further, when the traffic situation is such that the demand for communication resources is more, all the users cannot be served with sufficient quality of service. So, we need more resources. This is realized with the notion of sleeping pico cells operating at optical wireless bands. pico cells operate at optical wireless bands. These pico cells have capability of going into sleep mode when macrocell is capable of handling all the traffic to provide connectivity with sufficient QoS. When resources requirement is more, pico cells resume operating and serving the users with optical wireless band spectrum. Further, the vehicles are assumed to have some computing capability to help offload some computations of the central processor.
